Hey guys I am new here but I wanted to ask and get an opinion on this as we aren’t very handy ourselves.
My fiancée and I are finishing a lofted apartment area above a garage. We hired a family friend’s husband as our contractor and so far we haven’t made it far into the process.
He has torn down the old deck and put up a new extended one, which looks okay from what I can tell. However there are a few points on the stairs, especially the bottom step, that have splits in the wood. I am concerned that this may lead to loose boards or repairs needed later on.
Based on my one wood shop class in high school, I didn’t think this looked good, but like I said I am not very handy so I want a second opinion. Is this something I should have them fix or is this to be expected?
Would this still require removing the treads to apply or can you apply it underneath somehow?
in my experience, you don't need to disassemble. Apply generously and the oil would be absorbed in a couple of hours. You can put on a 2nd layer to be sure.
Paint protects from the outside and water seeps through its openings. Linseed oil saturates the wood to keep water out (it helps with insects too).
